ELECTRICAL EQUIPMENT & DESIGNEnclosures, Cabinets and FansIntelligent latching solutionsboost enclosure securityA conventional lock might keep undesirables out of your enclosure, but suppose you need a higherlevel of integrity; something a bit more sophisticated with a higher degree of monitoring capability?In many enclosure applications, physical security is amajor concern. Access control therefore plays a vitalrole in their design, construction and implementation.With increasing quantities of business-criticalhardware being deployed into enclosures, controlling andrestricting access to enclosures is a growing issue.A key element in enhancing security – and addingvalue to enclosure design through access control features– is the selection of reliable, intelligent latching systems.The right access control solution will also help reducecosts through energy efficiency and improve product andsystem reliability. Equally important is the selection ofaccess hardware which can be connected to existingsoftware to enable control and monitoring – such as whohas gained access and, when.Ulrike Sturman, Industry Marketing Manager forDiversified Technologies at Southco, explains: “With allthese vital issues to consider, it is no wonder thatcompanies are looking to collaborate with specialistpartners like Southco when it comes to actual accesshardware. At Southco, we have combined our expertise inengineered access solutions with innovative electroniclatching and access for the ultimate in intelligent, secure,ergonomic access control.”Southco provides a variety of electronic accesssolutions devices to suit application needs – from simplestandalone keypads and electronic keys to RF-based proxreaders and RF remote control systems. The company isadamant that its electronic latching technology offers theone of the best solutions in the market place, primarilyachieved by the operation of an electro-mechanicallatching system through a gear motor which makes itmore reliable and less-energy consuming.At the heart of the Southco offering is its flagship H3-EM Swinghandle – an electronic locking swing handlewith an eye-catching blue LED status indicator providingthe intelligent local and remote functionality of a manuallatching system with the addedbenefit of electronic locking andunlocking. The modular designaccommodates single or multipointlatching with a low power,gear motor driven lock mechanismand high security DIN lock manualoverride. The lock directlyintegrates with industry standard rack monitoring / accesscontrol systems and integrated sensors detect both lockedand latched status.Other key electronic access solutions (EAS) developedby Southco to meet increasing physical security andaccess demands include the push-to-close R4-EMelectronic rotary latch – enabling the convenience ofelectronic access control with the security of a proven, allmetalrotary latch design in a compact integrated package– and the EM-10 electronic keeper. This ‘next-generation’access control solution provides the convenience ofelectronic access and push-to-close operation in one unit.Its low installed cost, compact design and versatileinstallation options make it an easy, affordable solution fornew or retrofit enclosure applications.All Southco electronic access solutions provide anelectronic ‘signature’ each time the lock is actuated.Combined with a unique input credential, the system canprovide the necessary output to enclosure control andmonitoring systems. Each product has been designed asa drop-in replacement for existing mechanical latches.www.southco.com18INDUSTRIAL TECHNOLOGY • November 2010
Die-cast enclosureis sealed to IP66The latest addition to theextensive selection of diecastenclosures fromHammond Electronics is the1550Z family, a range of thick wall(3 to 4mm depending on size) IP66sealed boxes for use in applicationswhere impact protection andenvironmental sealing are primaryrequirements.The 18 industry-standard sizes inthe family range from 50x45x30mmto 223x147x83mm, and asstandard they are supplied in eithernatural with a smooth vibra-finish orin a tough black polyester powdercoated finish. Economically priced,the units offer outstanding value formoney, achieved by multi-impressiontools and automated machining andfinishing during manufacture.Environmental sealing is achievedthrough a combination of a tongueand groove construction and a preformedone-piece silicone rubbergasket; to ensure the integrity of theseal, the fixing screws are outsidethe gasket area. Depending on thesize, the lid is secured with two, fouror six stainless steel <strong>machine</strong> screwsgoing in to factory-tapped holes toaid repeated opening and closingwww.hammondmfg.com19
